## ✨ Features
- 🔧 **Tool call visualization** — see what your agent is doing in real-time: colored badges, visible parameters, expandable results. The killer feature missing from every other chat UI.
- 💬 **GPT-like interface** — sessions in a sidebar, switch between conversations. Familiar if you've used ChatGPT or Claude.
- 📋 **Multi-session navigation** — browse all active sessions including cron jobs, sub-agents, and background tasks
- ⚡ **Live streaming** — watch the agent think and write token by token
- 📊 **Token usage tracking** — progress bars per session so you know how much context is left
- 🖼️ **Inline images** — generated or read images render directly in chat with lightbox preview
- 🎯 **Chat-focused** — no settings menus or config panels cluttering the screen. Just the conversation.
- 🎨 **Themes** — Dark, Light, and OLED Black modes with 6 accent colors. Persisted per-browser.
- 🧠 **Thinking/reasoning display** — see the agent's reasoning process in collapsible blocks with elapsed time
- 🔍 **Message search** — Ctrl+F to search and navigate through conversation history
- 📐 **Split view** — open 2 sessions side by side with a resizable divider
- ✍️ **Syntax-highlighted input** — real-time markdown coloring as you type (code blocks, bold, links)
- 🔀 **Drag & drop reorder** — organize sessions in the sidebar by dragging, order persists across reloads
- 📋 **Raw JSON viewer** — inspect full gateway message payloads for debugging
- 🗂️ **Channel icons** — Discord, Telegram, cron, and other session types shown with distinct icons
- 📤 **Export conversations** — download any session as a formatted Markdown file
- 🌐 **i18n** — English and French built-in, easy to extend
- 🔔 **Notification sounds** — subtle audio chime for new messages (toggleable)
- ⌨️ **Keyboard shortcuts** — navigate sessions, toggle sidebar, search, and more without touching the mouse
- 📱 **PWA support** — installable as a progressive web app with offline caching and auto-updates
- ♿ **Accessible** — skip-to-chat link, focus-visible outlines, semantic HTML, `prefers-reduced-motion` support, ARIA live regions
## 🚀 Quick Start
### Docker (recommended)
```bash
docker run -p 3000:80 ghcr.io/marlburrow/pinchchat:latest
```
Open `http://localhost:3000` and enter your OpenClaw gateway URL + token on the login screen.
Or use Docker Compose:
```bash
curl -O https://raw.githubusercontent.com/MarlBurroW/pinchchat/main/docker-compose.yml
docker compose up -d
```
### From source
**Prerequisites:** Node.js 20+, an OpenClaw gateway running and accessible.
```bash
git clone https://github.com/MarlBurroW/pinchchat.git
cd pinchchat
npm install
cp .env.example .env
npm run dev
```
Optionally edit `.env` to pre-fill the gateway URL:
```env
VITE_GATEWAY_WS_URL=ws://localhost:18789
VITE_LOCALE=en # or "fr" for French UI
```
### Production build
```bash
npm run build
npx vite preview
```
Or serve the `dist/` folder with nginx, Caddy, or any static file server.
## ⚙️ Configuration
All configuration is optional — credentials are entered at runtime via the login screen.
| Variable | Description | Default |
|---|---|---|
| `VITE_GATEWAY_WS_URL` | Pre-fill the gateway URL on the login screen | `ws://<hostname>:18789` |
| `VITE_LOCALE` | UI language (`en` or `fr`) | `en` |
> **Note:** The gateway token is entered at runtime and stored in `localStorage` — it is never baked into the build.
## 🎨 Customization
PinchChat stores all preferences in `localStorage` — no server-side config needed.
### Themes
Click the palette icon in the header to switch between:
| Theme | Description |
|-------|-------------|
| **Dark** (default) | Zinc-based dark theme, easy on the eyes |
| **Light** | Clean light mode with white backgrounds |
| **OLED** | Pure black backgrounds for OLED screens |
| **System** | Follows your OS dark/light preference |
### Accent Colors
Six accent colors are available: **Cyan** (default), **Violet**, **Emerald**, **Amber**, **Rose**, and **Blue**. The accent tints buttons, links, progress bars, and user message bubbles.
### Other Preferences
These settings persist across sessions:
- **Sidebar width** — drag the right edge to resize
- **Session order** — drag & drop to reorder; pinned sessions stay on top
- **Syntax highlighting** — toggle the `</>` button in the input area
- **Split view** — open two sessions side by side (icon in header)
- **Language** — switch between English and French via the globe icon
- **Message drafts** — input text is preserved per-session when switching

### Key Components
| File | Role |
|---|---|
| `src/hooks/useGateway.ts` | WebSocket connection, auth, message streaming, session management |
| `src/components/LoginScreen.tsx` | Runtime credential entry (stored in `localStorage`) |
| `src/components/Chat.tsx` | Message list with auto-scroll and streaming display |
| `src/components/ChatInput.tsx` | Input with file upload, paste, drag & drop, image compression |
| `src/components/ChatMessage.tsx` | Markdown rendering, tool calls, thinking blocks |
| `src/components/Sidebar.tsx` | Session list with token usage bars and activity indicators |
| `src/components/Header.tsx` | Connection status, token progress bar, logout |
| `src/lib/i18n.ts` | Lightweight i18n (English + French) |
| `src/lib/gateway.ts` | WebSocket protocol helpers and message types |
### Data Flow
1. **Login** — User enters gateway URL + token → stored in `localStorage`
2. **Connect** — `useGateway` opens a WebSocket and authenticates with the token
3. **Sessions** — Gateway pushes session list; user selects one in the sidebar
4. **Messages** — Messages stream in via WebSocket frames; the hook assembles partial chunks into complete messages
5. **Send** — User input (+ optional file attachments) is sent as a JSON frame over the WebSocket

## 🌐 Adding a Language
PinchChat uses a zero-dependency i18n system. Adding a new language takes ~5 minutes:
1. **Open `src/lib/i18n.ts`** and duplicate the `en` object with your locale code:
```ts
const de: typeof en = {
'login.title': 'PinchChat',
'login.subtitle': 'Verbinde dich mit deinem OpenClaw-Gateway',
// ... translate all keys
};
```
2. **Register it** in the `messages` record (same file):
```ts
const messages: Record<string, typeof en> = { en, fr, de };
```
3. **Add a label** for the language selector:
```ts
export const localeLabels: Record<string, string> = {
en: 'EN',
fr: 'FR',
de: 'DE',
};
```
4. **Done.** The language selector, `VITE_LOCALE`, and browser auto-detection all pick it up automatically.
> **Tip:** TypeScript enforces that your new locale object has the same keys as `en` — missing translations won't compile.

## ❓ Troubleshooting
### Connection fails / "WebSocket error"
- Make sure your OpenClaw gateway is running and reachable from the browser
- Check the gateway URL format: `ws://host:18789` (or `wss://` if behind TLS)
- If PinchChat is served over HTTPS, the gateway **must** also use `wss://` — browsers block mixed content
- Verify the gateway token is correct (copy-paste from your OpenClaw config)
### Blank screen after login
- Open your browser's developer console (F12) and check for errors
- Ensure the gateway is running a compatible version of OpenClaw (v0.24+)
- Try clearing `localStorage` (Application tab → Storage → Clear site data) and logging in again
### Messages don't appear / sessions empty
- The WebSocket may have disconnected silently — check the connection indicator in the header
- If the gateway was restarted, PinchChat recon
